The SENTRON 3VA2463-6HN32-0KB0 is a 3-pole molded case circuit breaker rated for 630 A continuous at 40 °C, with a maximum breaking capacity of 242 kA at 240 V and 187 kA at 415 V — built for line protection in high-fault industrial distribution.
Breaking capacity and derating
Breaking capacity drops from 242 kA at 240 V to 187 kA at 415 V and 440 V, then to 121 kA at 500 V, and 9 kA at 690 V — the 690 V figure is the weak point; verify the available fault current at that voltage before specifying. Continuous current derates with ambient temperature: 630 A at 40 °C, 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. For a 40 °C panel, the 630 A frame is the headline rating; above that, apply the derate curve.
Physical fit and auxiliary options
Panel cutout and mounting hole pattern should match the SENTRON 3VA series; verify against the existing backpanel layout.
Maximum power loss is 162 W; operating temperature range -25 °C to 70 °C, storage -40 °C to 80 °C. The part carries a voltage trigger (yes) and a trip indicator (no) — the shunt trip provides remote tripping capability.
